Automotive Supplier Uses Marc to Improve Design of Stamping Tools

Company:

Tower International

Products:

Marc

Industries:

Automotive

Overview:

Stamping operations used to form metallic
automotive components can generate forces of
thousands of tons. The tools (die components)
that form these products must be able to
withstand this cyclic loading environment for the
life of the vehicle program. At the same time, it is
important to optimize the tool design in order to
be competitive. The evolution of higher strength
materials also adds to the challenge. The large
loads involved in forming these components
increase the challenge of designing robust
tools. Both linear and non-linear analysis must
be used to support the tool design process.

Results Validation:

“In order to get reliable predictions, we prefer
to use the nonlinear software Marc to solve these types of problems because it accounts
for the inherent nonlinearities of materials
experiencing plastic strain,” said Yueming
Cheng, Computer Aided Engineering
Engineer at Tower International. “In years
of using Marc and Mentat, I have found it
to be capable of accurately simulating a
wide range of nonlinear product behavior
under static, dynamic and multi-physics
loading scenarios. Marc is also one of the
commercial solutions in markets I am aware
of that has robust manufacturing simulation
capabilities, with the ability to predict general
damage, failure and crack propagation.”

Benefits:

Accurate simulations help
reduce risk of downtime and
lost revenues, by predicting
regions of potential failure
